Monotony

Re: http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2002Oct/0067.html

Where Patrick Stickler says:

     "This either seems non-monotonic" ...

This unwritten law that states that logic on the semantic web must 
always be non-monotonic is getting to sound more like a religious 
incantation than a pragmatic rule of thumb.  Personally I think it is 
time to examine this liturgy in the light of day.   Can anyone show me 
how you expect to always preserve monotony in a world where new 
knowledge can be discovered, facts can change, and anybody can say 
anything about anything ?

Incidentally, Guha, did I get the graph right?
